IMPROVEMENT IN WAGON-AXLES.

Specification forming part of Letters Patent No. 36,564, dated September 30, 1862.

To all whom it may concern.-

Be it known that I, R. P. GILLETT, of Viroqua, in the county of Bad AX and'State of Wisconsin, haveinvented a new andImproved Wagon-Axle; and I do hereby declare that the following is a full, clear, and exact description The axle A is made of iron or steel, or of wood with iron bands around it, and it is provided with a shoulder, a, in the ordinary manner. That part of the axle on which the wheel revolves is covered with a coating, B, of Babbitt metal or other similar composition from three-sixteenths to a quarter of an inch in thickness. This coating is put on in the following manner: the iron to be first washed with asolution of muriatic acid, zinc, and salammoniac, then the axle to be placed in a mold made for that purpose, and the heated metal poured in around it, when it will adhere to the iron and become completely solid.

The coating B extends up on the inside of the shoulder a, forming a shoulder, 12, which is cast hollow, with a cavity, 0, sutiiciently large to hold from one-half to a gill of oil, with an orifice or aperture, (2, at the top, where the oil can be poured in, and then corked up, so that it is not thrown out through the motions of the vehicle. A small channel, 6, extends from the cavity 0 along on the top of the axle to the aperture f, where it will be constantly oozing out, and by the action of the wheel when in motion it (the oil) will be carried around and over the whole surface of the axle. By these means the axle .is constantly lubricated and kept free from heating, however long and fast it may be run, the quantity of oil emitted through the aperture f being so small that there can be no chance for it to gum and thereby close up the oil-channel e.v If it should be found, however, that the oil passes out too rapidly, a small piece of wick may be passed through the channel e, which will permit of the oil oozing out at the aperture f sufliciently for the lubricating of the axle, as above stated.

This improvement may be applied to wooden axles as well as to such made of iron simply by placing two bands of iron around coated .with Babbitt metal, in the same manner as R. P. GILLETT.
